This article presents latest results of the search for top squark pair production in final states with one isolated lepton, jets, and missing transverse momentum in √s = 8 TeV pp collisions using L=21 fb−1 of data recorded with the ATLAS detector at the LHC. Two top squark decay scenarios are considered: (a) to a top quark and a long-lived undetected neutral particle (LSP), (b) to a bottom quark and a chargino, where the chargino decays via an on- or off-shellWboson to the LSP. The analysis also employs a new dedicated shape-fit method to target the challenging parameter region where is close to the kinematic boundary m(t) +m(LS P).
